I'm currently in the market for a home intercom and have started
looking around lately. So far, I've only found NuTONE products and information.
The NuTONE products seem rather outdated in an electronic sense of the word.
Has anyone in netland had any experience with other manufacturers of intercoms?
If so, how about any information on these others as to where I can order specs
and prices?
Thanks,

I recently bought a pair of Radio Shack FM wireless intercoms on sale for $40. Basic units. They work fine, although second floor to basement is pushing their range. -- David H. Copp

I also bought a pair of Radio Shack wireless intercoms -- they just plug into the nearest wall socket. There are some problems: on one entire floor of my 3-floor house, the intercom (either one -- I tried swapping 'em!) is very noisy for receiving, though it transmits just fine. Almost too noisy to understand the conversation. Both occasionally make loud, brief crackles and pops. But worst of all, every now and then they both SCREAM for hours and hours. Of course, I turn 'em off -- but once my tenant locked his in his room when he was out, and it screamed ALL NIGHT. ARRRGGGGHHH! I'd suggest getting a set with wires and going through the pain of laying the wires. --Chris Robertson

Broadcast to the Neighborhood using Wireless Intercoms
Some of the FM wireless intercoms transmit and receive in
the 46 and 49 MHz bands. These bands are shared with
cordless phones, remote control toys (i.e. Radio Shack
tanks/racing cars), and kids' toy walkie-talkies, etc.
Other wireless intercoms use the band of frequencies below
the commercial AM broadcast band. I had one that used a
frequency near 400 kHz.
Wireless intercoms that use radio frequencies are suscepti-
ble to interference, and afford no privacy. I can hear
neighbors' intercoms on my scanners and shortwave receivers.
